[0002] At present, in a display device, the connection between a backlight module and a display module is often a weak link in terms of waterproofing and dustproofing. To solve this problem, backlight strips are widely used at this connection to enhance the waterproofing and dustproofing performance. Existing strips are usually square. When installed, if the position of one side or one corner is placed incorrectly, it is easy to cause other corners to not fit properly, thereby affecting the display effect, and the entire strip needs to be reinstalled, which undoubtedly increases the installation difficulty and reduces the efficiency. Content of the Utility Model

[0003] Therefore, in view of the above problems, the utility model provides a waterproof backlight strip, which can not only effectively prevent the intrusion of moisture and dust, but also facilitate assembly.

[0004] To achieve the above object, the utility model adopts the following technical solutions: A waterproof backlight strip is arranged between a display module and a backlight module, and includes two horizontal strips and two vertical strips that can enclose to form a square frame, and connecting strips connecting the horizontal strips and the vertical strips. Limiting grooves are respectively arranged at both ends of the connecting strips, and limiting blocks that can be adapted to the limiting grooves are arranged at both ends of the horizontal strips and the vertical strips.

[0005] Further improvement, each of the horizontal strips, vertical strips and connecting strips successively includes an upper glue layer, a high molecular polymer material layer and a lower glue layer from top to bottom.

[0006] Further improvement, a plurality of convex strips are respectively arranged on the upper surface and the lower surface of the high molecular polymer material layer, and each convex strip is parallel to the corresponding length direction of the strip where it is located.

[0007] Further improvement, the cross-sectional shape of each convex strip is semi-circular.

[0008] Further improvement, positioning holes are arranged on the connecting strips.

[0009] Further improvement, waterproof and anti-fouling coatings are coated on the outer surfaces of each of the horizontal strips, vertical strips and connecting strips.

[0010] By adopting the foregoing technical solution, the beneficial effects of the present utility model are as follows: The connection between the limiting grooves provided at both ends of the connecting rubber strip and the limiting blocks of the horizontal rubber strip and the vertical rubber strip is a detachable connection. Such a design makes it more convenient to assemble, repair or replace the rubber strip, reducing the maintenance cost and time. Among them, the rubber strip is provided with a high molecular polymer material layer, endowing the rubber strip with excellent physical properties such as high elasticity, high strength, wear resistance, etc., providing a certain buffering effect for the rubber strip and effectively preventing damage to the display module and the backlight module caused by factors such as vibration or temperature change. Further, a plurality of protruding strips are provided on the upper surface and the lower surface of the high molecular polymer material layer, forming a plurality of tiny air isolation layers at intervals between the rubber strip and the display module and the backlight module, further improving its sealing performance and waterproof performance. The protruding strips reduce the contact area between the rubber strip and the display module and the backlight module, facilitating its disassembly. In addition, the cross-sectional shape of the protruding strip is designed as a semi-circle, making the stress on the rubber strip more uniform and further extending the service life of the rubber strip. Further, positioning holes are provided on the connecting rubber strip. During installation, the rubber strip can be accurately fixed between the display module and the backlight module through the positioning holes, avoiding repeated positioning caused by inaccurate installation positions. Further, the outer surfaces of each horizontal rubber strip, vertical rubber strip and connecting rubber strip are coated with a waterproof and anti-fouling coating, which can effectively prevent moisture and stains from entering the interior of the rubber strip, keeping the rubber strip dry and clean, and enabling the rubber strip to maintain good performance for a long time.

[0016] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0017] Refer to Figures 1-3, this embodiment provides a waterproof backlight rubber strip, which is arranged between the display module and the backlight module. It includes two horizontal rubber strips 11 and two vertical rubber strips 12 that can enclose to form a square frame, and a connecting rubber strip 13 connecting the horizontal rubber strips 11 and the vertical rubber strips 12. Both ends of the connecting rubber strip 13 are respectively provided with limiting grooves 14, and both ends of the horizontal rubber strips 11 and the vertical rubber strips 12 are provided with limiting blocks 15 that can be adapted to the limiting grooves 14.

[0018] Among them, each of the horizontal rubber strip 11, the vertical rubber strip 12 and the connecting rubber strip 13 successively includes an upper rubber layer 101, a high molecular polymer material layer 102, and a lower rubber layer 103 from top to bottom. The upper rubber layer 101 and the lower rubber layer 103 are black. Multiple convex strips 1021 with a semicircular cross-sectional shape are respectively provided on the upper surface and the lower surface of the high molecular polymer material layer 102. Each of the convex strips 1021 is parallel to the corresponding length direction of the rubber strip where it is located, and the upper rubber layer 101 and the lower rubber layer 103 are respectively arranged on the convex strips 1021.

[0019] In practical applications, the connecting rubber strip 13 can be L-shaped or C-shaped, etc., to meet the shape requirements of different display modules. The high molecular polymer material layer 102 is made of materials such as rubber-based high molecular polymer materials, silicone-based high molecular polymer materials, plastic-based high molecular polymer materials, or fiber-based high molecular polymer materials, which have good elasticity and aging resistance. It provides a certain buffering effect for the rubber strip, effectively preventing damage to the display module and the backlight module caused by factors such as vibration or temperature changes. The design of the convex strips 1021 not only enhances the strength of the rubber strip but also helps the rubber strip to closely fit with the display module and the backlight module, reducing the intrusion of moisture and stains.

[0020] In this embodiment, the connecting rubber strip 13 is provided with positioning holes 131. During installation, the connecting rubber strip 13 can be accurately fixed between the display module and the backlight module through the positioning holes 131, avoiding repeated positioning caused by inaccurate installation positions. Then, through the cooperation of the limiting grooves 14 and the limiting blocks 15, the horizontal rubber strips 11 and the vertical rubber strips 12 are installed, making the overall rubber strip more convenient for assembly, maintenance, or replacement.

[0021] In this embodiment, in order to further effectively prevent moisture and stains from entering the inside of the rubber strip, keep the rubber strip dry and clean, and enable the rubber strip to maintain good performance for a long time, the outer surfaces of each of the horizontal rubber strip 11, the vertical rubber strip 12, and the connecting rubber strip 13 are coated with a waterproof and anti-fouling coating.

[0022] In practical applications, the connecting rubber strip 13 is configured independently. The horizontal rubber strip 11 and the vertical rubber strip 12 can be an integral structure. When in need of use, cut out corresponding lengths according to actual situations, and cut out limiting blocks 15 adapted to the limiting grooves 14 to adapt to display modules of different specifications, thereby improving the versatility and market competitiveness of the product.

[0023] Although the present utility model is specifically shown and described in conjunction with the preferred embodiments, those skilled in the art should understand that various changes can be made to the present utility model in terms of form and details without departing from the spirit and scope of the present utility model defined by the appended claims, and all of them fall within the protection scope of the present utility model.
